    • A control apparatus for controlling a three- or single-phase semiconductor power converter employing fixed-pulse switching patterns superposes a DC component on an AC output voltage, to suppress asymmetrical magnetization of a transformer connected to the power converter.The three-phase semiconductor power converter 1 provides an AC output. The voltage of the AC output is changed by the transformer 12. The control apparatus 14 for controlling the power converter 1 includes an asymmetrical magnetization suppressive controller 15 to generate a correction value for each of basic fixed-pulse switching patterns to be applied to three-phase switching elements of the power converter 1, a phase corrector 16 to switch the correction values from one to another at timing when no switching operation is carried out at any one of the switching elements, and a pattern generator 17 to correct the basic fixed-pulse switching patterns according to the correction value provided by the phase corrector 16 and provide the corrected switching patterns.
    • 用于控制采用固定脉冲切换模式的三相或单相半导体功率转换器的控制装置将DC分量叠加在AC输出电压上,以抑制连接到功率转换器的变压器的不对称磁化。 三相半导体功率转换器1提供AC输出。 交流输出的电压由变压器12改变。 用于控制功率转换器1的控制装置14包括:非对称磁化抑制控制器15,用于产生要施加到功率转换器1的三相开关元件的基本固定脉冲切换模式的校正值,相位校正器16 在不在任何一个开关元件中进行开关操作的定时将校正值从一个切换到另一个;以及模式发生器17,用于根据由相位校正器提供的校正值校正基本固定脉冲切换模式 并且提供校正的切换模式。
